Radicals Tammy Wallace Varina High. Perfect Squares A number is a perfect square if it is the product of a number and itself. The first 12 perfect squares:

Not all numbers or expressions have an exact square or cube root. If a number is NOT a perfect square or cube, you might be able to simplify it. Simplifying.

7.7 Operations with Radicals.  A or of radicals can be simplified using the following rules.  1. Simplify each in the sum.  2. Then, combine radical.

Simplifying Square Roots Simplifying Square Roots.

Radical Basics We will work with square roots, thus, you do not need to write the index. The index for square roots is 2.

In order to add or subtract radicals: All radicals must be simplified. Then, you combine “like” terms. Square-root expressions with the same radicand.

Multiplying and Simplifying Radicals The Product Rule for Radicals is given by: Note that both of the radicals on the left have the same index. Throughout.

Multiplying Radical Expressions Note that This example suggests the following. and

Example Multiply. Solution

Example Simplify by factoring: 100 is the largest perfect- square factor of 300.

Solution continued 27s 3 is the largest perfect third-power factor.

Example Solution Factoring into two radicals. If find a simplified form for f(x). Taking the square root.

continued We can check by graphing

We have used the product rule for radicals to find products and also to simplify radical expressions. For some radical expressions, it is possible to do both: First find a product and then simplify. Multiplying and Simplifying Solution ExampleMultiply and simplify. Multiplying radicands 4 is a perfect square.
